Two members of the Problem Solvers Caucus – Reps. Mike Gallagher (R-Wisc.) and Mike Bost (R-Ill.) – told Forbes they won’t vote for the bill, while another, Rep. Peter Meijer (R-Mich.), said he has a “tremendous amount of discomfort” with it.

Several caucus members and moderate Republicans said they are still undecided on the bill, and only two members of the caucus, Reps. Adam Kinzinger (R-Ill.) and Reps. Brian Fitzpatrick (R-Pa.), say they are supportive of it.

Progressives say they have dozens of votes to deny passage if at least $3.5 trillion in reconciliation spending is not passed by both chambers of Congress beforehand: Rep. Mark Pocan (D-Wisc.), one of the leaders of the Congressional Progressive Caucus, estimated 40 to 50 votes, and possibly more.
